fieldset.tx-powermail-pi1_fieldset {

/* Disable border */

border: none;

}

fieldset.tx-powermail-pi1_fieldset label {

/* Style labels */

display: block;

width: 150px;

float: left;

clear: both;

}

fieldset.tx-powermail-pi1_fieldset input,

fieldset.tx-powermail-pi1_fieldset select {

/* Style input fields */

width: 200px;

border: none;

border-bottom: 1px solid black;

margin-left: 10px;

}

div.tx_powermail_pi1_fieldwrap_html {

/* Increase margin between every field */

margin: 10px 0;

}

Maybe it's useful to add a div layer to the tmpl_formwrap.html at the end, to clear the floats like:

<div style=”clear: both”></div>

You can use more than only one fieldset to style your form with more columns.

So you should add two pages (fieldsets) to your form and choose “single step”.

fieldset.tx-powermail-pi1_fieldset {

/* Disable border */

border: none;

}

fieldset.tx-powermail-pi1_fieldset_1 {

/* Style left fieldset */

width: 45%;

float: left;

}

fieldset.tx-powermail-pi1_fieldset_2 {

width: 45%;

}

Maybe it's useful to add a div layer to the tmpl_formwrap.html at the end, to clear the floats like:

<div style=”clear: both”></div>
